4、 How it works

The melt flow rate instrument is a plastic extrusion instrument. It uses a high-temperature heating furnace to make the tested object melt under the specified temperature condition. The test object in this melting state is extruded through a certain diameter hole under a specified load. In the production of plastics, melt index is often used to express the physical properties of polymer materials, such as fluidity, viscosity and so on. The so-called melt mass flow rate refers to the average weight of each section of extruded sample converted to the extrusion amount of 10 minutes.
